Clarice the Brave

Clarice is a young ship mouse grieving the loss of her mother when a mutiny forces her onto a small, leaky boat with a dangerous cat. Worse, she is separated from her younger brother, Charles Sebastian, who is trapped aboard the great ship.
 
Clarice and Charles Sebastian were taught to always be careful—but they will need to grow bold if they are to survive . . . and find one another again.
